PATRICK (JUXXIXGIIAM, OF NE\V BEIYFORI), MASSAL'H['SET'IS, ASSIGXOR TO THE AMERICAN CARRIER ROCKET COMPANY, OF SAME lLAtE.

LINE-CARRYING ROCKET.

SPECIFICATION forming part of Letters Patent No. 395,881, dated January 8, 1889.

Application filed November 30.1887. Serial No. 256,502. (No model.)

To aZZ whom it may concern.-

Be itknownthat I, PATRICK CUNNINGHAM,

a citizen ot' the United States, and a resident of New Bedford, in theeonnty of Bristol and State of Massaehusetts, have invented certain new and useful Improvements in Roekets, of, j

ohjeet' ot' this eonstruet ion heing to form a which the following is a SDOGiilCfliiOt].

My invention relates espeeially to devices employed t'or earrying lines.&e., t'rom a fixed point through the air to a distant-e and has for its objeet the provision of a self-propelling projeetile, in eomhinat'ion with a tuhe adapted and arranged to arry a coiled line therein, simple to plaee in po sition,easy to fire, which may he directed with great aeeuraey, shall he strong aml durahle, and ot great power.

To attain the desired end my invention consists, essentially, in a head earrying the projectile (-harge, in eomhination with a tuhe adapted and arranged to eontain a 'eoiled line,

he hereinat'ter tirst l'ully tleserihetl, and then 3 pointed out in the elaims.

in the drawings, Figure l is a side ele\a tion of my improved selt'-propelling projeetile is a longitudinal seea-rrangement'otf all the parts. .l ig. I; isa hottom view oi the tiring-heml with the linea'arryingtnhe removed.

Like letters of rel'erenee wherever t'heyoeeur indieale eorresponding parts in all the tigures.

A is the hotly ol' the tiring-heathstrongly made of metal and serew-threaded at o u.

l; is a metal plug serened into llt)tl atl". is a serew-t hreaded projeelion in the een- ,and in eertain novel amt nset'ul eomhinations I ter of plug l) for the reeeption ot' the connection with the earrying-t'uhe.

N is a perforated disk or plate, the under side whereot' is eoneave, screwed within body A,ahove plug l), thus leaving a chamber between plug it and the tiring eomponnd, the

ehamher tor the distribution ot the propelling-gases.

in loat ling m v projeetile for use thediskX is plaeed in position and a spindle is passed into the hodyAin theusnalmanner. Alayer ot' elay,')l, or equivalent, non-eondueting material is then paeked upon disk N, and the tiring eompound I" is pat-iced thereahove. llug l) is serewed home helow the disk X.

[is a t'use protruding from one of the pertorations d in plug l).

(t is a eone-s haped eap. serew-lhreaded at 1 for engaging with the projeetion E upon plug l) and at for engaging with a tuhe, ll.

l is a har aeross the interior ol eap t to whieh the line is attaehed, as hereinafter deserihed. w

h is a plug. pret'erahly made of wood, said [plug heing pert'orated at -/rand seeured in the extremity of tuhe ll, opposite to eap (t.

it is a line eoiled in tuhe ll, to he (nrried hy the projeetile, the end heing seeured at the spot from whieh the projeetile is tired.

in assemhling the parts for use, the tiring eomposition is eompressed within the-hody ot the projeetile ahove the plate upon whieh rests the elay or other non-eonduetorot' heat.

A layer ot' elay, M, or equivalent non-eondnetor of heat, is also plaeed ahovethe tiring eompound. llate m and plug ll are plaeed in position and the eapt seeured there.-ihove. llug l) is serewed home against dish N and the t'usej'inseflted. ln eoiling the line it is wound upon a'suitahle mandrel, and the coil is theneovered with a layer of material R, whieh is a noreeondnetoroi heat-shell asasheslus--and ])lilt'ttl in the tuh e ll. 'lhe ohjeetl in so iiuu-ising the eoiled line is to preventaetion thereon hy the metal ol' whieh the tuheist'ormed and prevent hurningwhenthe projeetile is tired. After the line is put into the tuhe ii the plug K isseeured in plaee and the mandrel withdrawn, the extremity of the last coil of the line is secured to the bar G, and the other end of' said line projects from the plug K, as at Z. The tube II is connected to the projectile A by the cone-shaped portion G. The device, consisting of two parts-via, the firing-head and the carrying-t ubcbeing united, is now ready for use; and the end I of the line being secured, the projectile may be fired in ai1ydirection, paying out the line as it passes through the air to the objective poi at.

The tube H serves as a tail, en ablingmc to carry the line with great accuracy; and by coiling the line within said tube in the manner specified, so as to pay the same out as the projectile progresses in its flight, I am enabled to carry a line a greater distance than would be possible by dragging it after the projectile. The tube also serves to protect the line from injury by the heat generated by the burning compound or escaping gas. The connection G, being conical in shape and attached to the plug I) at the center thereof, prevents the interference of the tube H with the action of the escaping gas so as to retard the flight of the projectile.

Having now fully described my invention, what I claim as new therein, and desire to secure by Letters Patent, is

1. The combination, with the charge-carrying tube of a rocket, of a line-carrying tuI-o attached to and supported by the base of the same, said line-carrying tube tapering at its forward end toward the point of connection, as set forth.

2. The combination of a metal ro(-ket'ease, a metal choke, a metal fuse-piece having a central conical deflector formed integral with said fuse-piece, and a surrounding series of diverging vents opening on the rear surface of the fuse-piece.

3. The combination, with the explosive-carrying tube provided with a perforated disk, I), at its rear end, of a lbw-carrying tube at tached to said disk and entirely in the rear of the same, substantially; as set forth.

4. A line-carrying rocket consisting ot a head containing. the rocket-charge, the base of the head being provided with an external screw threaded projection, in combination with a carrying-tube having a tapering head en gagin g with said screw-threaded projection, set forth, and containing a coiled line to be paid out as the rocket passes through the air, substantially as shown and described.

The combination, with the firing-head, of a hollow line-carrying tube, said tube being substantially the same diameter as the head, and bein connected with said head at the center of the i also thereof, the extremity of the car rying-tube next to the firing-head tapering at an angle nearlycoincident with the vents for the )IO )ellin -"asos in the ba'se of said head internal cross-bar, ti, said cap having a screwthrea-ded IlOlfUl'itilUll therein for engaging with the projection from the base of the head carrying the tiring-charge, substantially as shown and describml.

T. The combination, with the body A, carrying the tiring-charge, of the plug 1), having )ortorations (Z passing thcrethrough at an angle to its axis, external screw-threaded projection, E, and the lilw-m'u'rying tube engaging with said projection, substantially as shown and des ribw'l.

H. The combination of an oxplosive-r-arrying tube, a lino-carrying luboatlaohed thereto, a line located within said latter tube, and a non-conducting jacket or easing between said line-carrying tube and said line, (or the purpose set forth.
